Connections • Before connecting the device to other devices, turn off the power for all the other devices. Before turning the power on or off for all devices, set all volume levels to minimum. • Use only speaker cables for connecting speakers to the speaker jacks. Use of other types of cables may result in fire. To avoid the possibility of malfunction/damage to the product or damage to other property, follow the notices below. ● Handling and maintenance • Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components. • Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel. • When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths. • When turning on the AC power in your audio system, always turn on the power amplifier LAST, to avoid speaker damage. When turning the power off, the power amplifier should be turned off FIRST for the same reason. • Be sure to observe the amplifier’s rated load impedance (see “Specifications”), particularly when connecting speakers in parallel. Connecting an impedance load outside the amplifier’s rated range can damage the amplifier. • When connecting the speakers with high impedance, be sure that the total rated input capacity of the speakers does not exceed the output power of the amplifier. • When using a high-impedance speaker connection, make sure the audio signal is passed through an 80 Hz or above high-pass filter before being input to the speakers. • Do not swing the speaker by its carrying band. • Do not place the speaker face down with the grille attached, as deformation of the grille may result. • When placing the speaker face down, always place it on a flat and smooth surface. • Do not touch the speaker driver unit. ● Protective circuit This speaker system has an internal protection circuit that shuts off the speaker unit when an excessive input signal is applied. If the speaker unit emits no sound, reduce the volume level of the amplifier immediately. The sound will return automatically in several seconds. ● About this manual • The illustrations as shown in this manual are for explanation only, and may appear somewhat different from your device. • The company names and product names in this manual are the trademarks or registered trademarks of their respective companies. • Do not insert your fingers or hands in any gaps or openings on the device (ports). • Do not rest your weight on the device or place heavy objects on it. • Do not operate the device if the sound is distorting.

Ensure that the strength of the ceiling rail is sufficiently strong. Pre-installation (Preparation of the Cable) Use stranded wire for cables attached to the ceramic terminal. Strip their insulation as shown in the figure and connect them. About 7 mm (0.3") Note Do not plate stranded wires by solder. Doing so will cause the wire to break. Note Prepare a cable gland of AVC part no. PGB 13.5-12B. CAUTION Use an appropriate tool for opening the hole. Otherwise, you may be injured if you open the hole with your bare hands. CAUTION Always take measures to prevent the speaker falling down. If the safety wire is too short, prepare another wire appropriate for the speaker weight and installation conditions. If the wire is too long, should the speaker fall, the wire may break as a result of too much strain. CAUTION • Do not over-tighten the attachment screw. Otherwise, the attachment screw and clamp will break. • Do not turn any screws other than attachment screw (located beside the U mark). Otherwise, the speaker may fall or malfunction. 5 Set the Line Voltage/Impedance and Power Select the line voltage/impedance (100V/70V/8Ω) and power tap for 100V/70V line distributed system, by rotating the tap selector switch on the front side of the speaker with a flat-blade screwdriver. 4.2 Push up the speaker slowly into the ceiling, taking care not to trap the cable. The illustration indicates the setting at 30 W for 100 V line and 15 W for 70 V line. CAUTION • The “X” position should not be selected. The 8Ω position should be selected for 8Ω audio systems only. If the setting is incorrect, it may cause malfunction of the speaker and amplifier. • Make sure the amplifier is switched off before operating the tap selector switch. 3.3 Loosen the terminal screws of the ceramic terminal with a flat-blade screwdriver, insert the cables into each terminal and tighten the screws. Pull on the cables to make sure they are tightly secured and will not come loose. 1 Cut Out a Hole in the Ceiling 1.1 Put the supplied cutout template to the ceiling and draw a circle by tracing it. Make sure to use the cutout template so that hole is the correct diameter. Clamp 4.1 Attach the safety wire to the safety wire ring, and connect the wire to an independent support point, such as a joist. 6 Attach the Grille Earth* Fit the grille to the baffle front and turn it clockwise. + Note If you use a circular cutter, set the diameter with the cutout template. – 1.2 Cut the hole by tracing the circle. Be careful to prevent chips or powder entering your eyes while cutting the hole. 2 Install the Tile Rails and O-ring 2.1 Insert the two tile rails through the cut hole and place them on the ceiling surface within your reach. Be sure that each tile rails are oriented as shown below. 2.2 Insert the folded O-ring through the cut hole and open it in the ceiling. 2.3 Secure the O-ring and tile rails with supplied two screws through either slot of both O-ring brackets. * Use the Earth terminal as necessary.
